Thanks Kevin
I was thinking that the small chaff might not be much of a problem.
I collected some Heuff seed heads this afternoon and found the there were some open seed capsules at the bottom of the stem while there was still a bloom at the end of the stem. I cut off the bloom and the top capsule if it was not dry enough. I don't want mold. Some of them were dropping seed right into the bag as I put them in.
I also have 2 semp stems that are fastigated. I kept them seperate from all others. I wonder if they are worth keeping and growing this seed or not. I am not much of a fan of crested semps. hmmm any advice from someone more experienced?
